Xiaomi M365, 1S and Pro 2: won't charge, or the charger light stays green when plugged in

You plug in your M365, M365 Pro, 1S or Pro 2 and the battery bars don't climb, or the scooter won't turn on at all after sitting for a while. There are two causes: a faulty charger, or a battery that has over-discharged from not being charged (Mi Electric Scooter FAQ, 1S, Lite and Pro 2 FAQ). The short answer: test the charger on its own first, then read the charger light while it's plugged into the scooter.

Most likely cause

On the 1S, Lite and Pro 2, the charger light means this when it's connected to the scooter (1S, Lite and Pro 2 FAQ):

• Red: charging normally.
• Steady green while connected, battery not full: the battery is deeply over-discharged and has to be replaced.
• Flashing red and green: a shallow discharge, which charging can recover.

Over-discharge happens when a scooter sits for weeks on a low battery. The damage from over-discharge is permanent and isn't covered by warranty (Mi Electric Scooter FAQ).

Other causes to rule out

• A faulty charger: plug the charger into the wall with nothing connected. No light or a red light here means the charger is faulty and should be replaced. Green is normal (Mi Electric Scooter FAQ).
• A hot battery: on the 1S and Pro 2, a red temperature light means the battery is above 50°C. Shut it off and let it cool (1S, Lite and Pro 2 FAQ).
• Cold: avoid using the battery below -10°C or above 40°C (Mi Electric Scooter FAQ). Charge indoors at room temperature.

How to confirm

1. Plug the charger into a working wall outlet with nothing connected. Green means the charger is probably fine. Red or nothing means replace the charger.
2. Check the charge port and the charger plug for dirt, bent pins or moisture. See check your charger.
3. Bring the scooter to room temperature.
4. Connect the charger and watch the light. Red is good. Flashing red and green means leave it charging. Steady green on a scooter that won't turn on points to deep over-discharge.
5. A shop can check that the charger puts out about 42V, the output of a working charger. Leave any measurement on the scooter itself to the shop.

Fix options

Keep charging a shallow discharge (easy)

If the light flashes red and green, leave it on the charger for the full charge, about 5 hours. For storage, charge to about 80 percent before storing for more than 30 days and top up every few months. See store your battery for winter.

Replace the charger (easy)

If the charger fails the wall test, replace it with one made for your model.

Replace the battery (pro)

A steady green light on a scooter that won't power up means Xiaomi's answer is a new battery. Use Xiaomi after-sales through the Xiaomi contact page or a shop. A battery is a big part of the scooter's value, so read repair or replace first.
